In the Republic of Ireland the title was used by the first person elected in a multi-seat local government ward. The Local Government Act of 2001 abolished the title as part of a modernisation of local government, and as such none of the Councillors elected in the local elections of 2004 hold the title Alderman.

Historically, the term "alderman" was used for those persons elected to a municipal council to represent the wards. As women were increasingly elected to municipal office, the term "councillor" slowly replaced "alderman", although there was some use of the term "alderperson". Today, the title of "alderman" is rarely used, except in some cities in Alberta and Ontario as well as some smaller municipalities elsewhere in the country that retain the title for historic reasons.
